So recently the mono/stereo switch went on my 1960a. Im looking now to make it a mono input only for 16ohms since that is what I normally use. Im going to use the existing quick connect wiring in there but can someone tell me what kind of jack to get and where to get it (every detail helps, im new to this!)? Also will I be able to hook up the quick connect wiring to the jack? Trying to make this as easy as possible. I did check the connections and speakers to def determine it was the switch. I played with the switch a few times and was able to get a close to 16 (15..) reading but then a second time would read like 20-30 ohms.
